Nincomycin producer the marine bacteria BAC-9912 was mutagenesis with UV-irradiation and NTG. Chemic reagent ,Two high yield strains 9912-72U(obtained from UV-irradiation treat) and 9912-2U-32N(obtained from NTG treat) were obtained.

• 宁康霉素(Nincomycin)产生菌BAC-9912 经紫外线单因子和亚硝基胍化学试剂诱变；筛选获得两株高产菌株9912-7-2U(UV 处理获得)和9912-2U-32N(NTG 处理获得)；其摇瓶发酵效价分别为17646.；4iu/ml 和21780
